Description of problem:
SELinux is preventing /usr/bin/evince-thumbnailer from 'write' accesses on the file .mate_desktop_thumbnail.W8PJ5W.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that evince-thumbnailer should be allowed write access on the .mate_desktop_thumbnail.W8PJ5W file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep evince-thumbnai /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
